This ultimate high-capacity bundle combines the innovative Delipow DLP-5510 10-slot charging case with 10 pieces of high-performance Delipow AA 4000mWh 1.5V rechargeable lithium batteries in a stylish gradient blue finish. The DLP-5510 charging case features a modern Type-C input (DC 5V 3A), delivering a stable 350mA charging current per slot for 1.5V AA
lithium batteries across all 10 slots. Its exterior boasts a premium woven carbon-fiber texture, offering a sleek, durable, and modern aesthetic. Equipped with a precision smart chip, it utilizes a 1.6V±0.05V cut-off voltage and a ≤100mA cut-off current, automatically stopping charging to prevent overcharging and significantly extending battery lifespan. The case is built with a strong magnetic closure that withstands 5000 open/close tests, ensuring secure storage and easy access. The included 4000mWh AA batteries feature a massive 4000mWh energy capacity, a constant 1.5V voltage output, and a powerful 4A continuous discharge current (6.5A peak) to handle high-drain devices. With 1500-cycle long life, intelligent battery repair, and patented explosion-proof technology, this kit is the ultimate high-performance, large-capacity power solution for your smart locks, camera flashes, wireless microphones, and high-drain electronics.

Q1: How long does it take to fully charge the included 4000mWh AA batteries?
A1: Based on the charger's 350mA per-slot output and the standard charging formula (Capacity × 1.25 ÷ Current), it takes approximately 3 hours to fully charge a 4000mWh AA battery.
Q2: What is the advantage of the 4A high discharge current?
A2: The 4A continuous discharge current (6.5A peak) allows this battery to power high-drain devices such as camera flashes, wireless microphones, and high-performance RC cars. It delivers instant, powerful energy without the voltage drop or lag experienced with standard batteries.
Q3: What is the "Intelligent Battery Repair" function?
A3: When a battery has been over-discharged (left at 0% charge for a long time), the charging case can intelligently detect this and apply a safe micro-current to reactivate and repair the battery, effectively restoring it to a healthy charging state.
Q4: What safety features does this battery have?
A4: This battery is protected by a patented explosion-proof technology (Patent No. CN202411913698.6). It includes a full range of protections including over-current, over-voltage, over-charge, over-discharge, short-circuit, and over-temperature safeguards, ensuring safe and reliable operation.
Q5: What is the advantage of the woven carbon-fiber texture on the charging case?
A5: The premium woven carbon-fiber texture not only provides a modern, high-end look and feel but also enhances the case's durability and resistance to wear, making it more resistant to scratches and fingerprints during daily use.
